Randomized Controlled Trial
Does shaving the incision site increase the infection rate after spinal surgery?
A prospective randomized clinical study. ⋯ The shaving of the incision site immediately before spinal surgery may increase the rate of postoperative infection.

A prospective study. ⋯ DSA may be a reliable indicator for predicting the spinal residual growth potential in IS patients, but it should be correlated with menarchal status and chronologic ages.

Prospective imaging study of patients undergoing surgery for cervical compressive myelopathy. OBJECTIVES.: To investigate whether the classification of increased signal intensity (ISI) on magnetic resonance imaging (MRI) in patients with cervical compressive myelopathy reflects the severity of symptoms and surgical outcome. ⋯ Preoperative ISI on T2-weighted sagittal MRI was correlated with patient age, duration of disease, postoperative JOA score, and postoperative recovery rate. Patients with the greatest ISI had the worst postop erative recovery. Classification of ISI can be a predictor of surgical outcome.

Controlled in vitro trial. ⋯ Endplate-to-endplate PMMA augmentation restores the biomechanical properties of vertebrae in clinically relevant anterior wedge fractures. Our preliminary data suggest that biomechanical models with only 25% compressive deformation unlikely form a good model to assess the mechanical effects of cement augmentation in osteoporotic fractures.

Conventional and phase-contrast magnetic resonance (MR) imaging were used to evaluate the morphology and cerebrospinal fluid (CSF) flow dynamics at craniocervical junction in adolescent idiopathic scoliosis (AIS). ⋯ Peak CSF velocities through foramen magnum were not significantly different in AIS subjects despite the presence of low-lying cerebellar tonsils. This might be explained by the compensatory effect of larger foramen magnum in AIS subjects.
